To all whont it may concern.-

Be it known that I, HARRY HARDEN, a citizen of the United States, residing at London, in the county of Madison and .State of Ohio, have invented a new and usefulCutting Implement, of which the followingis a specification. 1

The invention relates to improvements in,

cutting implements.

The object of the present invention is to improve the construction of cuttingimplements and to provide a simple, inexpensive, and efficient cuttin implement adapted to be employed for avariety of purposes and capable of enabling great force to be exerted invention consists in the construction and. novel combination and arrangement of" parts, hereinafter fully described, illustrated" in the acconpanying drawings, and pointed out in the claims hereto appended, it being, understood that various changes in the form proportion, size, and minor. details ofconstruction within the scope of the claims may be resorted to without departinggfio'mthe spirit or sacrificing any of the advantages of."

the invention.

In the drawings, Figure 1 is a plan view of a cutting implement constructedin accord ance with this invention. Fig. 2 is an ene larged longitudinal sectional view of the outer portion of the cutting implement,

illustrating the arrangement offthe gearing. and closing the blades and for Fig. 1. Fig. 7 is a transverse sectional-view taken substantially on the line 7''? of Fig.1. Fig. 8 is a transverse sectional view taken substantially on the line 8 8 of Fig. 1. Fig. 9 is a detail view of one of the blades.

Fig. 5 is a longitudinal Fig. 6 is a longitudinal sectional view taken substantially on the line 6' Got Like numerals of'reference designate corresponding parts in all the figures of the drawin s.

ldesignates a frame or casing constructed of suitable metal andcomposed of two par allel sides or plates placed apart and connected'by. suitable walls'2 and 3, located at the side edges and outer endof the frame or casing. The frame or casing, which is tapered at its outer end, forms a guide for a pair of cutting-blades 4, provided with inner longitudinalcutting, edges 5, extending inwardly fromlthe outer ends of the blades, preferably to a point beyond the center of'the same and terminating short. ofthe inner ends of the blades; but'the cutting edges may be of any desired length to adapt the implement to the character of' work to be performed. The cutting edges are formed by beveling the blades atone face, the other face of each blade being smooth, as clearly illustrated in Fi 7 ofthe drawings. This will enable the bla des to cut off. a horn as closely to the head of an animal as desired. In removing the horn it is preferable to out into the hide about a quarter of an inch to remove the horn close to the roots, and the form of the blades shown will enable this result to be obtained byusin the instrument withthe flat faces of the blades against the headof the animal.

The outer ends of the blades are cut at an angle at'their outer edges to provide tapering portions, and the angularly-disposed eeges 6 are adapted'to engage and extend between a pair of guide-rollers 7, located at the outer end'of the casing and spaoedfapart to receive the tapered portions of the blades. The guide-rollers are mounted on suitable pivots 8, but any other. suitable antifriction guiding device may be employed, if desired. When the blades are moved longitudinally toward the outer end of the casingor frame 1. they arev forcedinwardly by the opposite guiderollers, and when they are moved in the opposite direction they are separated.

The casing is also provided at its outer portion with a pair of outwardly-converging slots 9, forming guides or ways for inner pivots 10 of a pair of outer oscillatory links 11. The links 11, which are extensible, are composed oftwo sections 12 and 13. The section 12 is. tubularand receives the other section 13, a coiled spring being housed within thetubular section and interposed between bla es.

one end of the same and the inner end 15 of end of the said section 13 is bent at an angle to provide an outer pivot 16. The tubular section is provided with an inner end wall having a central aperture to receive the section 13. v The ivot 10 at the inner end of the link 11 is formed integral with the tu bular section 12 and operates in the slots 9. The terminals of the pivots 10 and 16 are threaded to receive nuts, as shown, and the extensible pivots or links connect the outer portions of the blades with the frame or casing and permit the necessary longitudinal and lateral movements of the blades.

The inner ends of the blades are pivoted to "arms 17 of a pair of pivotally-mounted members 18, which are provided with terminal grips or handles 19, as clearly illustrated in Fig. 1 of the drawings. These operating members are in the form of substantially L-shaped levers and are connected with the frame or casing at opposite sides of the inner end thereof by means of bolts 20 orother suitable fastening devices, which pierce the levers and pass through longitudinal slots 21 of the frame or casing. The pivots 20 are located at the inner ends of the arms, which are connected with the said. blades at an intermediate point by pivots 22. The proximate ends of the arms. 17 are enlarged and provided with curved series of teeth 23, which mesh, whereby the operating levers or members 18 are caused to swing inwardly and outwardly in unison and to rovide a uniform movement of the The arms 17 of the operating levers or members are arranged at an obtuse angle to the body portion thereof, and the said levers are provided at the angle at their outer edges with curved series of teeth-24:, which mesh with longitudinal racks 25 of the frame or casing. The longitudinal racks 25 consist of teeth extending along the frame or casing at the'interior of the side edges thereof, as clearly shown in Fig. 2 of the drawings. The inner end of the frame or casing is provided with extensions or enlargements 26, which are provided with the said racks 25. The curved series of teeth 24 and the racks 25 rovide outer gearing which operate simu taneously with the outer gearing formed by the teeth 23, and when the operating levers or membersare swung inwardly or outwardly the. blades are moved laterally or transversely of the device to open. and close.

them and are also given a limited longitudinal movement to provide a shear out, such longitudinal movement being effected by the outer gearing. The arms 17 of the operating members or levers provide link connections between the-inner ends of the blades and the frame or casing, and they are slotted or bifurcated to form two spaced side portions,

between which are arranged the inner ends of the blades. One of the side portions of each arm is extended to form the said inner gearing, and arm terminates short of the toothed side portion to provide an ear for supporting the blade and the pivot 22.

The inner ends of the blades are rovided with rectangular openings 27, in wiich are arranged removable plates 28, which have eccentricallyarranged pivotopenings 29,

the other side portion of each located closer to one of the longitudinal edges of the plates than to the other, whereby the pivot-openings of the plates may be arranged different distances from the longitudinal edges thereof by sim ly reversing the plates 28. These reversib e plates 28 are adapted to be changed after the blades have become worn and will enable the cutting edges to be brought closer together. Any other suitable means, however, may be emloyedfor effecting an adjustment of the lades.

In order to enable great power to be exerted on the operating levers or members for cutting a large horn or for any other cutting operation requiring excessive power, a windlass is provided. The windlass consists of a shaft 30, mounted in suitable bearing-openings of a pair of arms 31 and having a crankhandle 32 at one end for rotating it to wind up a metallic strap or other flexible connection, of the operating members or levers and its other end secured to the shaft 30 of the other operating member or lever. The arms or lates 31 are suitably secured to the ,side aces of one of the operating members or lewhich has one end connected with one IOO vers, and their other ends are connected by a transverse pin or rivet 34. The other member or lever is provided with a pair of ears 35, which support a pin or rivet for securing the outer end of the strap 33 between the ears. I

The windlass-shaft is adapted to be rotated for winding the flexible connection 33 on it, and it will enable the cutting-blades to be moved inwardly with the necessary force to effect the cutting operation. The casing is provided at its outer end with a projecting eye 36 to enable the cutting implement to be hung on a nail or othersupport when not in use.

The frame or casing is provided with opposite circular openings 37, adapted to receive the horn to be severed from the head of an animal; but it will be readily apparent that the openings may be varied in size and shape to adapt the cutting implement to the character of the work to be performed.
